'Twilight' stars enjoy jet boat ride

Co-stars Kristen Stewart and Taylor Lautner, who are currently visiting Australia for a promotional tour for the series's third film, reportedly thought that the tourist attraction was "hardcore".

A spokeswoman for Oz Jet Boating told The Daily Telegraph: "They wanted to get wetter - they said they don't have anything like it in America and thought it was hardcore."

Stewart, however, reportedly upset fans by refusing to pose for photographs. One crowd member said: "She was in a bad mood because of the photographers. She was swearing at them. She tried to run into a restaurant but it was locked."

The pair are scheduled to appear at Luna Park today for a public interview.
